Yes, Powdery Mildew - use a copper based product to spray for it - not necessary to remove leaves if spots are still small like in the pics - if spray is effective you will see the spots turn brown/black indicating mildew is dead. Spray every 10-14 days

Looks like mildew, perhaps from too much humidity or if plants are too close together.

Oh! ok, thanks for your answer! I guess that's the problem, the plants aren't together, in fact the tomato is the only one that's in a separated container. I've tried a mix of water and baking soda but it haven't work yet, actually some leaves are getting yellow. What can I do?!

Sure does look like mildew. Cut off the affected leaves so it does not spread. The baking powder will help. Other than that, take a cutting from a healthy part of the plant and root in water. Throw the rest of the plant and dirt away. Disinfect the pot before using again. If the cutting does not get the mildew, plant again in good soil. If the pot is inside, it will benefit from air flow of some sort. That will help to prevent mildew.
